2. Connect field earth ground wire to ground screw or
earth ground via conduit system.
3. Wire the unit in accordance with Figure 6. See Table
2 for required supply wire temperature ratings.
4. As appropriate, install the fixture on the mounting
module.

NOTE: For use without field wire supervision installer can tie the two white leads together and tie the two
black leads together.
NOTE: DC polarity of circuit shown in supervisory state (signal inactive). Circuit polarity to reverse to activate signal.
Electrical supervision requires wire run to be broken at each device.
